Advantageous Effects

In an automatic bathing apparatus according to the present invention having the above-described configuration, by operating a rotation means that operates by electricity and that is installed at a far distance from the user, with a switch formed in a remote control or a relay means, a rotation motion is generated, and the generated rotation motion is transferred in order of a first flexible shaft means, the relay means, a second flexible shaft means, and a driving means, and when a rotation motion transferred to the driving means drives a rotation shaft of the driving means, a bathing means connected to one end of the rotation shaft rotates. Therefore, a user can safely and conveniently perform automatic bathing by contacting a rotating bathing means with a body without using a hand.

Because the bathing means can be detached, by selecting a bathing means in which a brush, a sponge, a scrubber, etc. are transplanted according to a desired bathing work, and coupling the bathing means to a rotation shaft of the driving means, a desired bathing work can be more easily performed.

Further, in a rotation means that is buried in a wall or whose one side is buried in a wall, a rotation motion can be generated and transferred by an electromotor and transferred in a plurality of directions of the outside of the rotation means by a multiple transfer means installed within the rotation means. Accordingly, the rotation means can be freely disposed at the left side, the right side, the upside, etc. of the user.

Further, a flexible shaft means that receives a rotation motion of the rotation means is divided into a first flexible shaft means and a second flexible shaft means, and a relay means for connecting a rotation motion is provided between the first flexible shaft means and the second flexible shaft means. Accordingly, even if the rotation means buried in a wall and the driving means are disposed apart far, the first flexible shaft means and the relay means are buried in a wall, and the second flexible shaft means to which the driving means is connected can be freely moved. Accordingly, even if the flexible shaft means is long, bathing can be easily performed by handling only the driving means freely connected to the second flexible shaft means

Further, at an end part of the second flexible shaft means, a connector means having a coupling member that receives a rotation motion and that detachably couples to the relay means is formed, and the connector means is detachably coupled to the relay means.

Further, when transfer of a rotation motion is disturbed by trying to forcedly stop a driving bathing means, or overly twisting of the second flexible shaft means, the motor is in an overload state, and thus in order to protect the motor, an idle rotation means is provided within a connector means. If a rotation motion is disturbed by power over some limit, an idle rotation induction means provided within an idle rotation means is operated, and the transferred rotation motion is disconnected and is converted to an idle rotation. Thereby, a rotation of the second flexible shaft means and the bathing means is suspended, and an overload of the motor due to continuous rotation is prevented.

Further, the relay means that is buried in a wall or whose part is buried in a wall and that connects and transfers a rotation motion of the first flexible shaft means to the second flexible shaft means can be easily detached from the second flexible shaft means. Accordingly, by using separation or a rotation motion of the relay means, an operation means for another purpose can be also operated.

Further, by using, as a spring, which is a flexible shaft means, a metal spring, or a resin spring, which is an insulator, electricity safely can be improved.

Further, because a cross-section of a hooking means formed at one end of both end parts of a spring provided within the first flexible shaft means and the second flexible shaft means is formed in a quadrangular shape, when receiving or transferring a rotation motion, a rotation motion can be easily hooked.

Further, a rotation motion transfer end part of the rotation means and an end part of a rotation motion transfer reception part and transfer part of the relay means rotate together by connecting to a quadrangular hooking means.

Further, in an automatic bathing apparatus according to the present invention having the above-described configuration, the driving means includes: a guide pipe that guides a flexible shaft means; a driving bevel gear that receives a rotation motion of the flexible shaft means guided through the guide pipe; a driven bevel gear that interlocks with the driving bevel gear; a housing that has a pair of bevel gears therein; and a rotation shaft that is detachably attached to a bathing means and that is formed in the other end of the driven bevel gear.

The driving means includes:

a lubricating oil supply means that supplies lubricating oil to the rotation shaft; a packing pressing means that is provided in a periphery of the rotation shaft to press a packing for suppressing permeation of water; one end of the rotation shaft that is formed in a metal means; a water discharge means that discharges water permeated to the inside to the outside; a bathing device protection means that protects a bathing device; a length adjustment means that adjusts a length of the handle; and a coupling means that couples other operation device means to a periphery of a rotation shaft to which a bathing device is detachably attached; and a hand hooking means that hooks and uses a hand. Accordingly, the driving means is conveniently and usefully used as follows.

In a portion of a packing that blocks permeation of water in a periphery of the rotation shaft within the driving means, a lubricating oil storage and supply device for continuously supplying a lubricating oil is formed, and thus even if the driving means is used for a long time period, the lubricating oil storage and supply device assists a long period sustainable lubrication function between the rotation shaft and the packing and simultaneously performs a sustainable waterproof function.

Further, when packing of a periphery of the rotation shaft is worn due to long time driving of the rotation shaft within the driving means, in order to reduce a replace frequency of the packing, if a pressure is applied to a packing by rotating and advancing a packing pressing means without rapidly replacing the packing, the packing of an elastic rubber material is pushed, and one end of the pushed packing close contacts with the rotation shaft and waterproof property is improved and thus a lifetime of the packing is extended.

Further, in the driving means, a stainless steel pipe is installed at one end of a periphery of the rotation shaft contacting with the packing within the driving means, and thus upon friction of the packing and the rotation shaft, wear durability of the rotation shaft is improved.

Further, in the driving means in which the rotation shaft drives, due to wear of packing of a periphery of the rotation shaft or other reasons, if water is permeated into the driving means, driving of the bevel gear assembly, etc. within the driving means is disturbed. In this case, water can be briefly discharged through a water discharge means formed by penetrating the inside and the outside of one side surface of the driving means without discharging water by disassembling the driving means.

Further, in the driving means, even if the user puts a driving means in the floor while the mounted bathing device rotates, by the bathing device protection means provided apart a clearance from a periphery of the rotating bathing device, only one side of the bathing device protection means and the driving means rotates while contacting with the floor and the bathing device. Further, the side of the rotating bathing device is prevented from contacting with a skin.

Further, in the driving means, usually, it is preferable to shortly use the handle of the driving means in view of handling, however in order to extend a length of a handle for a bathing operation of a portion in which a hand does not touch well such as the back, if extending and fixing the handle, because the handle is extended by pulling in a connection direction of the second flexible shaft means, the bathing means can easily contact with the back and bathing of the back can be easily performed.

Further, a coupling means that uses a rotation motion of the rotation shaft of the driving means and that couples other operation device means to the driving means of a periphery of the rotation shaft is provided, and by coupling and using the other operation device means to the rotation shaft and the coupling means, a rotation motion of the rotation shaft is transferred to the other operation device means. For example, if protrusions for massage are formed at one side of the other operation device means, and at the inside thereof, if an eccentric weight that receives a rotation motion of the rotation shaft to convert the rotation motion to a vibration motion is provided, in a portion in which the user wants, a massage effect can be obtained.

Further, if taking and using the hand hooking means in a hand, the driving means can be taken more securely. Even if the driving means is dropped from the hand, the driving means is not dropped from the hand by the hand hooking device, and because the driving means is positioned at the hand with only the back of the hand without gripping the driving means, and a person who having weak hand power or in which use of a hand is uncomfortable can easily use the driving means.

Further, when an interior angle of two central axes of the driving bevel gear and the driven bevel gear within the driving means is an acute angle, centrals axes of a handle formed at a periphery of an extension of a straight line of the driving bevel gear and a bathing means coupled to a rotation shaft of an end part of an extension of the driven bevel gear forms an acute angle, and thus when bathing the back by raising a hand over a shoulder, a contact between the back and a contact surface of the bathing means is easily performed.

Further, if burying one end of the relay means and the rotation means, and the first flexible shaft means in a wall, protrusion of the relay means and the rotation means into a bathroom space is minimized and thus it is preferable in view of an appearance and electrical safely.

Further, when performing a bathing operation by contacting the bathing means with a body, in order to widen a contact surface thereof to the maximum, by forming a bathing surface of the bathing device such as a brush, a sponge, and a scrubber to be recessed, adhesion to a skin line having a round external form increases and bathing efficiency improves.

Further, in the automatic bathing apparatus that ejects water of the tap, while performing various works such as bathing, bathroom cleaning, and a partial clothing washing, water necessary when performing the work can be supplied voluntarily without a separate water hose or a shower device, so that bathing and a cleaning work can be very conveniently performed.

While a rotation of the driven bevel gear 56 is transferred to the second spring 47 of the second flexible shaft 7, if the second spring 47 or the bathing device 8 of the driver 9 that receives a rotation of the second spring 47 is disturbed by an external force over some degree, an idle rotation induction device 59 a operates and disconnects transfer of a rotation motion, and the transferred rotation motion performs an idle rotation at one end of the idle rotation induction device 59 a.

FIGS. 11 and 12 illustrates a first idle rotation induction device in which protrusions for inducing an idle rotation are vertically disposed in an idle rotation induction device shown in FIGS. 9 and 10, FIG. 11 is an enlarged exploded perspective view of an idle rotation induction device in which idle rotation induction protrusions are vertically arranged, and FIG. 12 is a cross-sectional view illustrating an assembled shape of a first idle rotation induction device of FIG. 11. The following description is described in detail with reference to FIGS. 11 and 12.

In the first idle rotation induction device 59 a consisting of a first driving transfer member 60 and a first driven transfer member 61 formed in a pair of an upper portion and a lower portion, because a quadrangular bar 58 b positioned at the center of the first upper driving transfer member 60 is inserted into a quadrangular hole 31 (see FIG. 9) of the driven bevel gear assembly 55, the first upper driving transfer member 60 receives a rotation motion, and at the lower end of the quadrangular bar 58 b, a first disc 65 in which the quadrangular bar 58 b is vertically positioned at the central part thereof is integrally formed. At many places of the first disc 65, a plurality of elastic pieces 66 that have vertically elasticity are formed, and a first protrusion 67 for hooking is formed in a lower direction at an end part of the elastic pieces 66.

In a lower part of the first disc 65 of the driving transfer member 60, as the first driven transfer member 61 that receives a rotation motion of the first disc 65, in a second disc 71 in which a plurality of second protrusions 70 for hooking to first protrusions 67 of the elastic piece 66 of the first disc 65 are formed in a circular shape and arranged in a line and a periphery of an upper edge of the second disc 71, a cylinder 69 for holding the first disc 65 of the first driving transfer member 60 is integrally formed.

In the idle rotation induction device 59 a having the above-described configuration, when a first protrusion 67 of a first driving transfer member 60 side engages with a second protrusion 70 of a first driven transfer member 61 side, a rotation motion is transferred from the first driving transfer member 60 to the first driven transfer member 61. If transfer of a rotation motion receives a disturbance force over some degree due to an action, for example, twisting of the second flexible shaft 7 or forcedly stopping by taking a rotating bathing device 8 with a hand of disturbing transfer of a rotation motion in the second spring 47 of the second flexible shaft 7 or the bathing device 8 of the driver 9 formed under the first driven transfer member 61 while transferring a rotation motion, the first upper protrusions 67 and the lower protrusions 70 are hooked to each other. Accordingly, if a disturbance force over some limit generates under the second flexible shaft 7 while transferring a rotation motion, the elastic piece 66 in which the first protrusions 67 of the first driving transfer member 60 side is formed is pushed up, then the elastic piece 66 drops again by an elastic force, the first upper protrusion 67 and the first lower protrusion 70 are hooked, the elastic piece 66 is pushed up, and due to such a continuous operation, an idle rotation is induced.

At many places of an outer circumference surface of a horizontal side of the disk 74, a plurality of elastic pieces 77 that has elasticity horizontally toward an opposite side of the center of the disk 74 are formed, and at the outside of the end part of the elastic piece 77, a third protrusion 76 for hooking is formed. In a lower part of the disk 74, as a second driven transfer member 83 for receiving a rotation motion of the disk 74, a cylinder 79 in which a plurality of fourth protrusions 80 for hooking the third protrusion 76 of the disk 74 are formed in an inner circumference surface thereof is integrally formed, and at many places of an inner circumference surface of the cylinder 79, a hooking jaw 78 is formed so that an upper cylinder does not escape, and at the lower end of the cylinder 79, a quadrangular hole 72 in which an opening is formed in a lower direction is formed at the center thereof, and the quadrangular spring 48 (see FIGS. 9 and 10) formed in an end part of the second spring 47 of the second flexible shaft 7 is inserted into the quadrangular hole 72, and thus a rotation motion of the disk 74 is transferred to the second spring 47.

In the second idle rotation induction device 59 b having the above-described configuration, when third protrusions 76 of the second driving transfer member 82 engages with fourth protrusions 80 of the driven transfer member 83 side, a rotation motion is transferred from the second driving transfer member 82 to the second driven transfer member 83. If transfer of a rotation motion is disturbed in the second spring 47 or the bathing device 8 of the second flexible shaft 7 under the driven transfer member 83 while transferring a rotation motion, the elastic piece 77 in which protrusions of the driving transfer member 82 side are formed is pushed in a central direction of the disc 74 and is restored to an original position by an elastic force and is moved in an opposite direction of the center, and opposite third protrusion 76 and fourth protrusion 80 are hooked by each other and the elastic piece 77 is pushed in a central direction of the disc 74 and is restored to an original position, and due to a continuous operation, an idle rotation is induced.

FIG. 32 is a perspective view of a driver in which a bathing device cover is removed and a handle is slidably extended.

The driver 9 extended to the second flexible shaft 7 side while the handle 10 slides along the guide pipe 164 and is used for well contacting the back when bathing the back in which the hand does not well touch.

FIG. 33 is a longitudinal cross-sectional view of a driver.

FIG. 34 is an exploded perspective view of the driver of FIG. 33.

FIGS. 33 and 34 are described in detail as follows.

The driver includes a guide pipe 164 that guides the second flexible shaft 7 that transfers a rotation motion received in order of the motor housing 1, the first flexible shaft 3, and the relay 5 into the driver 9; a driving bevel gear assembly 160 and a driving bevel gear 161 that receive a rotation motion of the second flexible shaft 7 through the guide pipe 164, a driven bevel gear assembly 149, a driven bevel gear 150 that interlocks with the driving bevel gear 161; a housing 151 that has a pair of bevel gear assemblies (160,149) therein; and a rotation shaft 144 that is detachably attached to the bathing device 8 and that passes through the inside and the outside of the housing 151 at the other end of the driven bevel gear assembly 149 and that is integrally formed. The bearings (147 a, 147 b, 147 c 147 d) are formed in an outer circumference surface of an intermediate step of the driving bevel gear assembly 160 and the driven bevel gear assembly 149 and revolve in an inner side surface of the housing 151.

Further, the driver 9 of the automatic bathing apparatus according to the present invention includes a lubricating oil storage 158 that supplies lubricating oil to a packing 146 enclosing a rotation shaft of the inside of the housing 151 a; a packing pressing end plate 145 that is provided in a periphery of the rotation shaft of the inside of the housing 151 a to press a packing 146 for assisting waterproof of the rotation shaft; a stainless steel pipe 159 that is provided in a periphery of a rotation shaft contacting with the packing 146; a water discharge hole 153 that discharges water permeated to the inside of the driver 152 to the outside; a stopper 154 that blocks the water discharge hole 153; a bathing device cover 142 that encloses one end of the bathing device 8; a handle 10 that can adjust a length; other operation device coupling member 175 in which a massage device is coupled to the housing of a periphery of a rotating shaft to which the bathing device 8 is detachably attached; and a hand hooking member 230 (see FIG. 19) that can use by hooking a hand.

This is described in detail.

A lubricating oil storage 158 is formed within the rotation shaft 144 provided within the housing 151 a of the driver 9, and a passage 148 that supplies from the lubricating oil storage 158 to the outer circumference surface of the rotation shaft 144 is formed, and an oil feeder 156 that feeds to the lubricating oil storage 158 is formed at an at an end part of a bar of the rotation shaft 144 protruded to the outside of the housing 151 a, and an oil feeder stopper 155 that detachably blocks the oil feeder 156 is also formed, and lubricating oil of the lubricating oil storage 158 is continuously supplied to the packing 146 side enclosing the passage 148 through the passage 148. Here, it is preferable that lubricating oil of a paste phase having viscosity is used so as to continuously and slowly supply. Further, an oil absorbent 157 made of a fiber material is provided within a storage to supply continuously and more slowly lubricating oil.

Further, in a periphery of the rotation shaft 144 of the bathing device 8 side of the driver 9, an outer circumferential surface of an end plate 145 for pressing a packing 146 that is inserted into the driver 9 and that is formed in the periphery of the rotation shaft 144, and that blocks penetration of water from the outside is a cylinder formed in two steps consisting of a small circumference and a large circumference, and the screw groove 162 for fastening is formed in an outer circumference surface of a large circumference, and even if a rotation shaft 144 rotates so that a locking direction of the screw is identical to the rotation shaft 144 of the rotation shaft 144, due to a vibration, the end plate 145 is not locked.

Further, a screw groove is formed in an inner circumference surface side of the housing 151 a contacting with an outer circumference surface of the large circumference, and a rotation hole 171 for rotating the end plate 145 by hooking a tool is formed at one end of the end plate 145. When rotating while advancing the end plate in an inside direction of the driver, a side part of a small circumference pushes and pressures a packing 146 of a rubber material and thus the pressed and pushed packing 146 close contacts with an outer circumference surface of the rotation shaft 144 within the housing 151 a due to the pressure.

In the end plate 145, when the packing 146 tightly inserted into a periphery of the rotation shaft 144 has been used for a long time period, in spite of a lubrication action of a lubricating oil, an inner circumference surface of the packing 146 is worn by a rotation of the rotation shaft 144 and thus external water of the housing 151 a permeates into a gap of the packing 146 and the rotation shaft 144. At this time, by advancing while rotating the end plate 145 in an inside direction of the housing 151 a without replacing the packing 146, when the packing 146 is pressed to one side of the end plate 145, the packing 146 is pushed by the pressure and the pushed packing 146 of a rubber material more close contacts with an outer circumference surface of the rotation shaft. Because a washer 172 b and a bearing 147 a are sustained at the packing 146 of an opposite side of the end plate, the packing 146 is no longer pushed.

In this way, because permeation of water is prevented, lifetime of the packing can be extended without immediate replace of the packing 146.

Because a periphery of one end of a rotation shaft enclosing the packing 146 in the rotation shaft of the driver 9 is formed with a stainless steel pipe 159, the stainless steel pipe 159 minimizes wear of the rotation shaft 144 from friction of the rotation shaft 144 and the packing 146. This is because when the entire rotation shaft 144 is made of plastic, the rotation shaft is worn due to a friction with the packing 146 and a weight thereof reduces, compared with when the entire rotation shaft 144 is made of metal.

Further, at one end of the housing 151 of the driver 9, due to wear of the packing 146 of a periphery of the rotation shaft 144, in order to discharge water permeated to the inside, water can be simply discharged through the water discharge hole 153 penetrating through the inside and the outside of the housing 151 without disassembling the housings (151,151 a). A stopper 154 is formed in the water discharge hole 153, and as a screw groove is formed at both sides with which the water discharge hole 153 and the stopper 154 contact, the water discharge hole 153 and the stopper 154 may be separated and may be securely coupled.

Further, because the water discharge hole 153 are disposed around the bevel gears (150, 161), in order to check the bevel gears (150, 161) or to smoothly rotate the bevel gears (150, 161), the water discharge hole 153 can perform a functional of a check hole for checking lubricating oil.

Further, because the stopper is made of a transparent material, water permeated to the inside of the housing 151 can be viewed without opening the stopper.

Because a plurality of protrusion type coupling members 170 detachably coupled to one end of the housing 151 a are formed in a bathing device cover 142 enclosing one side of an opposite side of the bathing surface of the bathing device 8, the coupling members 170 can be detached, as needed, and a bathing device cover coupling member 177 having an L-shape groove to be coupled to the coupling member 170 of the bathing device cover 142 is formed in a multi-step of an outer circumference surface of the housing 151 a.

Further, in the bathing device cover 142 of a recess form enclosing one side of the bathing device 8, when the driver to which the bathing device 8 is attached faces the upside direction, in order to easily discharge water pooled at the inside of the recessed bathing device cover 142, a water flowing hole 143 is formed at many places of the bathing device cover 142.

Even if the bathing device 8 is put at the floor for a moment while rotating, the bathing device cover 142 allows the rotating bathing device 8 not to contact with the floor and prevents the side of the bathing device disk 141 in which washing hairs are transplanted from contacting with a skin. Further, when the bathing device 8 receives an impact such as drop of the driver 9 to which the bathing device 8 is attached, if the side of the bathing device 8 receives an impact, the rotation shaft 144 to which the bathing device 8 is coupled and bevel gears (150,161) which are an extension part of the rotation shaft 144 are badly affected and thus a function for preventing this is performed.

FIGS. 35 to 38 illustrate the handle length fixing device 165 a of FIGS. 33 and 34. The following description is described according to a configuration thereof.

FIG. 35 is an enlarged exploded view of a handle length fixing device shown in FIGS. 33 and 34.

FIG. 36 is a view illustrating the handle length fixing device of FIG. 35 that is assembled to be installed between a guide pipe and a handle.

FIGS. 34, 35, and 36 are described in detail as follows.

In an inner circumference surface of the handle length fixing device 165 a provided in an outer circumference surface of a lower end part of the guide pipe 164, as shown in FIG. 34, a fixing groove 185 of the guide pipe 164 to be fixed together with a fixing protrusion 184 (see FIG. 34) of the handle length fixing device 165 a formed in an outer circumference surface of a lower end part of the guide pipe 164 is formed, and in a lower part thereof, because a fixing ring 186 (see FIG. 34) for supporting and fixing the handle length fixing device 165 a supports, the handle length fixing device 165 a is fixed to a lower end part of the guide pipe 164.

A first circular circumference 196 and a second circular circumference 197 that are deviated in a vertical direction of the drum type member 192 of the handle length fixing device 165 a and that is parallely formed are a little smaller than a diameter of an inner circumference surface of the handle 10 and are formed in an outer circumference surface 195 of the drum type member 192, and only a part of an outer side surface of a central wide arc 193 of a ring 191 whose opening is formed at one side thereof and that has a narrow end part contacts with an inner circumference surface of the handle 10. Therefore, when gripping and fixing the driver 9 or the guide pipe 164 with one hand and gripping and turning the handle 10 to the right side with the other hand, due to a contact friction of the inner circumference surface of the handle 10 and the central wide arc 193 of the ring 191, as the ring 191 rotates together, a friction between the circumference surface of the central wide arc 193 of the ring 191 and an eccentric outer circumference surface of the drum type member 192 increases and thus the outer circumference surface of the ring 191 puts between the inner circumference surface of the handle 10 and the outer circumference surface of the drum type member 192 and is fixed due to a pressure thereof. In order to release the fixation, if fixing the guide pipe 164 and rotating the handle 10 to the left side, a protrusion 194 formed at one end of the ring 191 contacts with a hooking jaw 198 formed at one end of the outer circumference surface of the drum type member 192, whereby a rotation of the ring 191 stops and a pressure therebetween is released. When a pressure is released as described above, the handle 10 can freely vertically move in a periphery of an outer circumference surface of the guide pipe 164, and if the handle 10 rotates again at a desired position, both the handle 10 and the guide pipe 164 are fixed. If the handle 10 rotates after extending toward the second flexible shaft 7 by a desired length along the guide pipe 164 as described above, both the handle 10 and the guide pipe 164 are fixed by the handle length fixing device 165 a, and a total length of the driver 9 is thus extended.

FIG. 37 is another enlarged exploded view of the handle length fixing device 165 b whose end part is formed in a wide ring in the handle length fixing device of FIG. 34.

FIG. 38 is a view illustrating the handle length fixing device 165 b of FIG. 37 that is assembled to be installed between a guide pipe and a handle. The following description is described in detail with reference to FIGS. 37 and 38.

The drum type member 192 is the same as that of FIGS. 35 and 36, and an operation mechanism of a wide ring 200 of a shape that is provided in an outer circumference surface of the drum type member 192 and in which an opening is formed at one side and in which a cross-section of both end parts is wide and that becomes gradually narrow when advancing to a central arc and that has a wide end part is similar to that of FIGS. 35 and 36. When a wide arc 201 of the ring 200 rotating together while contacting with an inner circumference surface of the handle 10 approaches in a right rotation direction of an eccentric outer circumference surface of the drum type member 192, the wide arc 201 of the ring 200 is strongly pressed by the outer circumference surface of the drum type member 192 and the inner circumference surface side of the handle 10 and is in a sandwich state, and the handle 10 is thus fixed. If the wide arc 201 of a ring 200 is released in an opposite direction, a pressure is released and the handle 10 can be freely vertically moved.

FIGS. 39, 40 and 41 is a view illustrating another handle length fixing device in which a first clamp is installed in an arc-shaped guide pipe and handle.

FIG. 39 is a perspective view of a driver in which a length of a handle is shortened and that is fixed with a clamp.

FIG. 41 is an exploded perspective view of a handle of a driver and a clamp.

The following description is described in detail with reference to FIGS. 39, 40 and 41.

A first clamp 203 is provided at one end of an outer circumferential surface of an arc-shaped handle 10 a provided in an outer circumference surface of an arc-shaped guide pipe 164 a bent with a smooth curved line, and at one end of an outer circumference surface of the arc-shaped handle 10 a to which the first clamp 203 is adjacent, a first hinge member 209 and a second hinge member 202 are formed in the outer circumference surface of the handle 10 a and the first clamp 203 so that the first clamp 203 may be hinged in the outer circumferential surface of the handle 10 a. At one end of the first clamp 203, a ground 205 protruded to be grounded with the guide pipe 164 a is formed, at the other end thereof, and a lever 204 for operating with a finger is formed to be hinged with the guide pipe 165 a.

If the lever 204 is dropped in a lower direction like the lever movement direction 205, the ground 205 positioned at the other end of the lever 204 is fitted to the guide pipe 164 a, and the guide pipe 164 a and the handle 10 a are fixed together.

In the first hinge member 209 of the handle 10 a, a pair of pin hooking jaw 211 connected to the pinhole 210 of the first clamp 203 is formed, and a gap 206 is formed between the pin hooking jaws 211. The first clamp 203 can be rotated in the gap 206 and be grounded to the guide pipe 164 a.

FIG. 43 is an exploded partial perspective view of the handle length fixing device of FIG. 42. The following description is described in detail with reference to FIGS. 42 and 43.

At one end of an outer circumference surface of the handle and an intermediate step of the second clamp 212 provided in an outer circumference surface of the handle, a first hinge member 209 and a third hinge member 214 are formed. A lever 215 is formed at the lower end of the second clamp 212 and at an upper end thereof, a hooking member 213 for hooking to a plurality of hooking holes 217 whose the inside is blocked and that are formed in an outer circumference surface of the guide pipe 164 b is formed. At the inside of the hooking member 213 of the second clamp 212, a spring 216 for allowing the hooking member 213 of the second clamp 212 to continues to apply a force to the hooking hole 217 of the guide pipe 164 b is provided, and the third hinge member 214 of the second clamp 212, the first hinge member 209 of the handle 10 b, and a pin 207 for penetrating the spring 216 are provided. A gap 206 is formed between the first hinge members 209 formed in the handle 10 b and thus the hooking member 213 freely contact with the hooking hole 217 of the guide pipe.

A guiding member 218 of a long protrusion is formed in an outer circumference surface of the guide pipe 164 b and an inner circumference surface side of the handle 10 b so that the handle 10 b only vertically moves in a straight line instead of moving in a lateral direction in the outer circumference surface of the guide pipe 164 b.

As in FIGS. 39 and 40, in FIGS. 42 and 43, the guide pipe 164 b and the handle 10 b may be curved in an arc shape, and as both the guide pipe 164 b and the handle 10 b are bent, if the handle 10 b is extended along the guide pipe 164 b, when performing a bathing operation of the back, a bathing surface of the bathing device 8 more easily contacts with the back.

FIG. 44 is a cross-sectional view illustrating a massage device.

FIG. 45 is a perspective view illustrating the massage device of FIG. 44.

The following description is described in detail with reference to FIGS. 44 and 45 together with other operation device coupling member 175 formed in the housing 151 a of FIGS. 33 and 34.

The massage device further includes a coupling member 175 in which the massage device 221 is coupled to the housing 151 a of a periphery of the rotation shaft 144 to which the bathing device 8 is detachably attached. A fastening member 176 having a detachable L-shape groove in an outer circumference surface of the cylindrical coupling member 175 so that the massage device 221 is not easily separated is formed.

A protrusion type fastening member 223 for the L-shaped groove is formed in the massage device 221, and the fastening member 223 is inserted into the L-shaped groove and fastened to the L-shaped groove by turning a little and at the same time, the rotation shaft 144 of the driver 9 is also inserted into the rotation shaft insertion device 224 of the massage device 221.

At the center of a side surface of the driver of the massage device 221, a rotation shaft insertion device 224 that is detachably coupled and that receives a rotation motion of the rotation shaft 144 is provided, and an operation device rotation shaft 225 of the massage device 221 that rotates with the rotation motion received from the insertion device is provided at the inside of the massage device, which is an opposite side of the rotation shaft insertion device 224. At an end part of the operation device rotation shaft 225, an eccentric weight 222 for generating a vibration when rotating is provided to generate a vibration by a rotation of the operation device rotation shaft 225. The vibration is transferred to the protrusion 228, which is a skin contact surface of the massage device and by contacting the protrusion 228 with a skin, a face beauty massage or a skin massage can be performed.

Further, the massage device 221 makes more rapidly a rotation motion of the operation device rotation shaft 225 and thus a vibration due to the eccentric weight 222 becomes larger and stronger, whereby the massage device 221 can be used as a massage device.

FIG. 46 is perspective view of a driver in which a hand hooking member is installed.

FIG. 47 is a perspective view illustrating a hand hooking member.

The following description is described in detail with reference to FIGS. 46 and 47.

A palm side grips the handle 10, and the back of the hand is hooked to a hand hooking device 231, and the hand hooking device 231 is hooked to each one side of a first handle attaching band 232 formed in an outer circumference surface of the handle 10 and at one end of a housing 151 around the handle 10 and a second attaching band 233 formed in an outer circumference surface of a lower end of the handle 10. One end of the hand hooking device 231 is fixed to the handle second attaching band 233, and the other end thereof passes through a through hole 234 formed in another first handle attaching band 232, and is attached to a velcro 235 formed in many sides of the hand hooking device 231, and thus by moving a position of the velcro 235 for moving and attaching according to a size of a user's hand, a length of the hand hooking device 231 is adjusted.

The first handle attaching band 232 and the second handle attaching band 233 are detachable from a periphery of the handle 10 or the housing 151 by a first velcro 236 and a second velcro 237 formed in itself and can be used as a hand hooking member 230 by attaching, if necessary, according to a user's inclination and can be used as the driver 9 by removing, if unnecessary. Therefore, such a hand hooking member 230 is especially necessary for an old person who has a weak arm force or a disabled person in which use of a hand is uncomfortable.

FIG. 48 is a partially cut-away perspective view illustrating two axes of a bevel gear of the driver having an interior angle of an acute angle.

If an interior angle of two central axes of the driving bevel gear 161 and the driven bevel gear 150 becomes an acute angle 239, the center of the handle 10, which is an extension line of the driving bevel gear 161 and the center of the bathing device 8, which is a extension line of the driven bevel gear 150 thus becomes an acute angle 239, and thus one end of the housing 151 becomes bent from the handle 10. After the handle 10 of the driver 9 is extended, when bathing the back over a shoulder while gripping the handle 10 with the hand, even if the hand is moved less toward the back or is raised less, the bathing surface 240 of the bathing device 8 more easily contacts with the back.

MODE FOR THE INVENTION

An operation of an exemplary embodiment of an automatic bathing apparatus according to the present invention having the above-described configuration is described in detail with reference to the drawings.

Because a plug for supplying electricity to the motor housing 1 is always inserted into an outlet, a switch 49 provided in the remote control 12 or the relay 5 is in a standby state that can operate the motor housing 1 and thus a user can operate the automatic bathing apparatus at anytime with the switch 49 of the remote control 12 or the relay 5.

When bathing with the automatic bathing apparatus, the user grips the driver 9 and inserts the bathing device 8 into the protruded rotation shaft 144 of the driver 9. After splashing water in a whole body or a body portion to bath, the user applies shampoo in the bathing surface 240 of the bathing device 8 or splashes water in the bathing surface 240 and lathers a body. Thereafter, if operating the motor 19 within the motor housing 1 by pressing an operation button of the switch 49 of the remote control 12 or the relay 5, the motor 19 rotates, thus rotates the first gear 20 of a motor side and the neighboring second gear 21, and thus the rotation transfer shaft 22 rotates, and the transferred rotation motion is transferred to the first spring 36 within the first flexible shaft 3 connected to a coupler (one of 28 a, 28 b, and 28 c) extended and connected to one end of the rotation transfer shaft 22.

In this case, gears of directions that are not used among gears (29, 30, 24, 23) installed at a plurality of places of the first rotation transfer shaft 22 to transfer a rotation motion in a plurality of directions of the outside are removed, or moves a position thereof in order not to allow gears to contact, in order to decrease operation noise.

A rotation motion of the first spring 36 within the first flexible shaft 3 is transferred to the coupler (92 a or 92 b) of the driving bevel gear assembly (95 a or 95 b) within the relay 5 to rotate the driving bevel gear (96 a or 96 b), and to rotate the driven bevel gear 98 by interlocking with the driving bevel gear (96 a or 96 b), and to transfer the rotation motion to the connector 6 of the second flexible shaft 7 side through the coupler 92 c of the driven bevel gear assembly 97. The transferred rotation motion is transferred to the driver 9 through the second spring 47 within the second flexible shaft 7 and is transferred to the coupler 188 of the driving bevel gear assembly 160 of the driver 9 to rotate the driving bevel gear 161, the driven bevel gear 150 interlocking with the driving bevel gear 161, and the driven bevel gear assembly 149, and to rotate the rotation shaft 144 extended to one end of the driven bevel gear assembly 149, and thus rotates the bathing device 8 inserted into the rotation shaft 144 protruded to the outside of the rotation shaft 144. At this time, a rotation speed button appropriate to the user among various motor speed adjustment buttons of the switch 49 of the remote control 12 or the relay 5 is selected and operated.

If the rotating bathing device 8 to which bathing agent is applied slowly moves while contacting with a skin of a body, the rotating bathing device 8 removes sweat and fat on a skin, an aged horny skin, and dust while generating soup bubble due to a contact with a skin.

After such a bathing operation, a bathing is automatically performed with less force by bathing a bathing portion with water. After the bathing is terminated, the motor 19 of the motor housing 1 is stopped by pressing a stop button in the switch 49 of the remote control 12 or the relay 5.

Further, the bathing device cover 142 detachably attached to the bathing device 8 side of the driver 9 protects the side of the disk 141 of the rotating bathing device 8 among using from contacting with a body. Even if the side of the bathing device 8 is affected as the driver 9 is dropped to the floor, the bathing device cover 142 protects the rotation shaft 144 into which the bathing device 8 is inserted and connection parts within the driver, which are an extension part of the rotation shaft 144. The bathing device cover 142 can be easily removed by rotating when the user does not want.

Further, bathing of a region having difficulty in touching with a hand, such as a back can be easily performed by extending the handle 10 at a lower end of the driver 9 toward the second flexible shaft 7, fixing the handle 10 with the handle length fixing device (165 a, 165 b, 203, or 212), and extending a length of the driver 9.

In the above-described driver, the bathing device 8 to which a brush, a sponge, and a scrubber are attached is used according to user selection.

Further, according to a quality or an elastic degree of a bathing hair that is attached to the disk 141 of the bathing device 8 or that is transplanted, a rotation speed of the bathing device 8 is set to about 270 to 350 RPM even if there is a somewhat difference, at this rotation speed, water or soap bubble is little splashed from the bathing device 8, and an automatic bathing can be performed.

Further, in the automatic bathing apparatus, a hand hooking member 230 that is detachably attached to the driver 9 is provided. When the user fixes a first handle attaching band 232 and a second handle attaching band 233 formed in the hand hooking member 230 to one end of the handle 10 or the housing 151 around the handle 10 as needed, fixes then using velcros (236, 237), and the back of the hand is hooked by the hand hooking device 231 by inserting a hand into the hand hooking device 231 for connecting two of the first handle attaching band 232 and the second handle attaching band 233, and the palm of the hand grips the handle 10 of the driver 9. Because the velcro 235 is formed in the hand hooking device 231 itself, a length of the hooking device 231 can be adjusted by moving a bonding position of the velcro 235, a length of the hand hooking device 231 is adjusted according to a size of the hand. Accordingly, even if the handle 10 of the driver 9 is dropped, because the hand hooking device 231 is hooked in the back of the hand, the driver 9 is prevented from being dropped from the hand, so that it is helpful for a person having a weak hand force or an old and feeble person.

Further, when automatically massaging a face or a body in a bathroom using the automatic bathing apparatus, if the motor 19 within the motor housing 1 is operated by pressing the switch 49 of the remote control 12 or the relay 5 after inserting the massage device 221 into the rotation shaft 144 of the driver 9 and the other operation device coupling member 175 around the rotation shaft 144, the transferred rotation motion rotates the operation device rotation shaft 225 of the massage device 221 that receives a rotation motion by being inserted into the rotation shaft 144 of the driver 9, and the eccentric weight 222 rotating together with the operation device rotation shaft 225 is formed in an end part of the operation device rotation shaft 225 in an internal connecting part of the massage device 221 of the operation device rotation shaft 225, and thus the operation device rotation shaft 225 the eccentric weight 222 rotate and thus vibration movement is generated by the eccentric weight 222, and the vibration vibrates the massage device 221 and brings the protrusion 228 of the massage device into contact with a face or a desired body region, and thus the face or the desired body region is massaged. At this time, massage can be more softly performed by using an oil or a body shampoo, etc. as a lubricating oil agent in a skin contact region with which the protrusion 228 of the massage device contacts. Further, the massage device 221 can perform a function of a vibration massage device by performing a heavy vibration operation using the eccentric weight 222.

Further, when intending to clean a bathroom using the automatic bathing apparatus, the user inserts a cleaning device into the rotation shaft 144 of the driver 9 after sprinkling water on a desired cleaning part, and applies a cleaning agent in the floor or a wall to clean or a cleaning device for cleaning. Likewise, the rotating bathing device performs a cleaning operation while contacting with a cleaning portion together with cleaning agent by moving the rotating bathing device for cleaning while contacting the rotating bathing device for cleaning with a portion to clean after operating bathing device for cleaning, and by sprinkling water after the cleaning operation, a cleaning operation of a bathroom can be automatically operated. A rotation speed of the driver when performing a cleaning operation is more rapidly than that when bathing.

Further, by selecting a bathing device in which different kinds of bathing hairs are transplanted and inserting the bathing device into the driver according to use, a partial washing operation of clothing such as washing of sports shoes or heavy dirt of clothing can be automatically performed.

In a case of a wide bathroom, because a driver having a long flexible shaft is necessary, in order to extend and use a length of the second flexible shaft 7, a flexible shaft extension line can be connected and used between the connector 6 between the relay 5 and the second flexible shaft 7, and a connecting member that can be connected to the relay 5 and a connecting member that can connect to the connector 6 are formed at both ends of the flexible shaft extension line.

Further, when intending to supply water to an operation region while performing an operation such as body bathing, bathroom cleaning, and partial washing of clothing using the automatic bathing apparatus according to an exemplary embodiment of the present invention, by selecting the driver 9 a in which a water ejection device is formed, opening a shower water lever 276, and turning the tap 270, water of tap is discharged like shower water through the ejector 269 of the driver 9 a after passing through the external water supply pipe 274 and the water supply pipe 274 disposed within the second flexible shaft 7. By sprinkling the discharged water of a tap to an operation portion, bathing of a bathing portion can be performed and water may be discharged at the same time with a bathing operation and only a shower device function may be used with water ejected to the ejector 269 without a separate bathing operation.
